JE Pistons forged eight-piston kit for 5.4 3V Modular engines, configured to an 11:1 compression ratio. This set uses a 3.622 in bore with -10.1 cc piston volume sized to the application. Manufactured in the USA from 2618 aluminum, the design employs JE’s Forged Side Relief forging to cut friction and weight. Accumulator grooves and optional skirt coatings enhance ring sealing, reduce wear and help maintain consistent power in high-stress conditions.
